1 2007最后一篇,研究了一个星期,Hibernate3 Spring2 Struts2 环境搭配,参考 http://www.javaeye.com/topic/137793
2 准备工作
集成开发环境eclipse 3.2.
数据库 Sybase 12.5.4
架包
asm.jar
cglib.jar
commons-collections.jar
commons-lang.jar
commons-logging.jar
dom4j-1.4.jar
ehcache-0.7.jar
freemarker-2.3.8.jar
hibernate3.jar
jconn3
junit.jar
ognl-2.6.11.jar
struts2-core-2.0.9.jar
xwork-2.0.4.jar
spring.jar
struts2-spring-plugin-2.0.9.jar (如果没有配Spring做listener，放入这个包会报错)
jta.jar
antlr-2.7.6rc1.jar
3 环境结构
WebRoot
|-index.html
|-JSP Folders
|-META-INF
| |-MANIFEST.MF
|-WEB-INF
|-web.xml
|-lib (Folders)
|-classes (Folders)
|-classFolder
|-applicationContext-Action.xml
|-applicationContext-Dao.xml
|-applicationContext-db.xml
|-applicationContext-Manager.xml
|-struts.xml
|-(other struts.xml)
4 Web.xml配置

	<display-name>Struts Blank</display-name>

	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>
			org.apache.struts2.dispatcher.FilterDispatcher
		</filter-class>
	</filter>

	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>

	<welcome-file-list>
		<welcome-file>index.html</welcome-file>
	</welcome-file-list>
	-
	<listener>
		<listener-class>
			org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>
  <context-param>
 	<param-name>contextConfigLocation</param-name>
 	<param-value>classpath:applicationContext-*.xml</param-value>
 </context-param>
</web-app>

将filter配置成org.apache.struts2.dispatcher.FilterDispatcher
listener配置成org.springframework.web.context.ContextLoaderListener
context-param是配置Spring的applicationContext文件，如果不配默认位置是WEB-INF下的applicationContext.xml文件
5 applictionContext.xml配置
Spring的bean可以配置在一个文件中，也可以分开配置在WEB.xml的context-param中指定。
applictionContext-db.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<!-- Hibernate SessionFactory -->
	<bean id="dataSource"
		class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName">
			<value>com.sybase.jdbc3.jdbc.SybDriver</value>
		</property>
		<property name="url">
			<value>jdbc:sybase:Tds:10.40.34.156:5000/RedSaga</value>
		</property>
		<property name="username">
			<value>sa</value>
		</property>
		<property name="password">
			<value></value>
		</property>
	</bean>

	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource">
			<ref local="dataSource" />
		</property>
		<property name="mappingResources">
			<list>
				<!-- Add list of .hbm.xml files here
					<value>Vampires/model/Article.hbm.xml</value>
					<value>Vampires/model/Board.hbm.xml</value> -->
				<value>Vampires/model/User1.hbm.xml</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.HSQLDialect
				</prop>
			</props>
		</property>
	</bean>
</beans>

在applictionContext-db.xml中通过Spring2的org.springframework.orm.hibernate3.LocalSessionFactoryBean将hibernate3的SessionFactory配置成一个Bean
applictionContext-Dao.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans
	xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
	<bean id="UserDao"
		class="Vampires.dao.hibernate.UserDAOHibernate">
		<property name="sessionFactory">
			<ref local="sessionFactory" />
		</property>
	</bean>
</beans>

将bean SessionFactory 付值给dao的sessionfactory,（这里dao都是
都org.springframework.orm.hibernate3.support.hibernateDaoSupport的子类）
applictionContext-Manager.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans
	xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
	
	<bean id="UserManager" class="Vampires.service.impl.UserManagerImpl" scope="prototype">
	   <property name="userDao">
			<ref bean="UserDao"/>
		</property>
	</bean>
</beans>

将Dao传递给Manager
applictionContext-Action.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans
	xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
	
	<bean id="UserAction" class="Vampires.web.UserAction" scope="prototype">
	   <property name="usermanager">
			<ref bean="UserManager"/>
		</property>
	</bean>
</beans>

6 struts.xml配置
struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
    <constant name="struts.objectFactory" value="spring"/>
    <include file="example.xml"/>
    <!-- Add packages here -->
</struts>

将 <constant name="struts.objectFactory" value="spring"/>配上，这样Struts通过Spring的beanfactory寻找action bean
example.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
        "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

    <package name="example" namespace="/example" extends="struts-default">

        <action name="HelloWorld" class="UserAction">
            <result>/example/HelloWorld.jsp</result>
        </action>


        <!-- Add actions here -->
    </package>
</struts>

在class中指定为applictionContext-Action.xml中配置的action bean 的id ,通过上一步的<constant name="struts.objectFactory" value="spring"/>Struts会在springfactory中寻找UserAction
